HVAC contractors, and boiler maintenance specialists around the world for over ninety years. To be sure that we are providing our customers with the tools that they need, we talk to our customers, we listen to our customers, and we ask questions. In the past only two important questions needed to be answered: Can I get better fuel efficiency? and Is the ...

really important to do combustion testing? Looking at the flame color, shape and stability has been used as a “ rule of thumb” for many years but eyeballing will not allow you to opti- mize the efficiency, safety, or environmental compliance of your equipment. Just as doctors make use of the most sophisticated instrumen- tation possible when diagnosing their patients, the best way to make sure that yo ...

smoke can tell me a lot about combustion. How do they all relate to efficiency? Theoretically, peak fuel efficiency is achieved by “ per- fect” combustion, also called the Stoichiometric Mix (see charts #2 and #3). If it were possible to have perfect combustion, CO 2 would be maximized and O 2 would be at, or close to, zero in the flue gas stream. Because perfect combustion is not practically possible, m ...

and flue draft measurements** (0.04 to 0.06 inches H2O) insure that there is continuous negative pressure in the combustion system. Excess draft will increase your stack temperature and decrease your combustion efficiency. It is important to measure draft on the chimney side, well d o w n s t ream from a draft divert e r. This measurement will tell you if there is sufficient draft to move the flue gase ...

smoke? Smoke is best measured when the burners have stabilized, normally one minute after ignition for small combustion equipment. CA-16 Can oil furnaces and boilers produce CO? Oil burners, and any other piece of combustion equip- ment, will produce CO (carbon monoxide) when there is not sufficient mixing of O 2 and fuel for complete combustion. C O M B U S T I O N S A F E T Y CS-1 W hat is Carbon Monoxide ...

poisoning? The best way to prevent Carbon Monoxide poisoning is to make sure that your combustion equipment is func- tioning properly. Combustion air openings (vents, flues, exhausts and ducts) must be kept open, clean and free of blockages such as dirt, dust, lint and trash. Never obstruct a draft hood, wind cap or exhaust vent on any combustion appliance. Don’t store anything against or near the equipment that co ...

Visual inspection of the heat exchanger should always be done first. It may not be possible with visual inspec- tion alone to make sure that the heat exchanger has no cracks or pinhole leaks caused by corrosion. One sign of a cracked heat exchanger is a change of oxygen concentration in the flue gases of greater than 1/2% oxygen, or a change in the carbon monoxide level greater than 25 ppm. This change is ...

gases? Nitric oxide (NO) and Nitrogen Dioxide (NO 2) are the toxic gases which constitute NO X. All combustion processes can produce NO X. NO X emissions contribute to the formation of acids in the earth’s lower atmosphere; these acids contribute to the formation of acid rain. Additionally, NO X and hydrocarbons can react with sunlight to produce a potent respiratory irritant that is commonly called sm ...

TC-1 I’ve always been able to get along by eyeballing the flame. W hy should I use a mechanical or electronic instrument? As amazing as the human eye is, it is not capable of per- forming quantitative analysis of changing colors in widely varying surroundings and situations. The only quantifiable analysis that you can depend on is achieved through the use of mechanical or electronic instrumentation. TC-2 If mechanical instruments will ...

Simultaneously, the oxygen sen- sor is automatically spanned of 20.9 O 2 in air. Most manufacturers recommend that calibration using certified concentrations of test gases be done at least every six months. TC-7 How long do electrochemical sensors la ...
